California detective, Cory Pierce, facing charges in San Luis Obispo

LOS ANGELES (AP) -- Federal prosecutors say a San Luis Obispo narcotics detective is under arrest for allegedly performing official acts for two sources in exchange for cash, oxycodone and heroin.

U.S. attorney's spokesman Thom Mrozek says 39-year-old Cory Pierce was arrested Tuesday by FBI agents and has been charged with one count of bribery.

The six-year veteran allegedly cultivated a couple as sources after the man was arrested for heroin possession, saying the source could work off the charge by cooperating.

Pierce also allegedly influenced the man's probation officer to perform little or no supervision, and tipped off the couple to drug houses that were in danger of getting busted to help them avoid arrest.

Prosecutors say Pierce provided the couple methamphetamine that was still in police evidence bags on several occasions.
